Hello all, recently I have been experiencing an issue with the imx uart on i.MX6ULL SoC, on the tty console (no flow control, 1152008n1), chars after the 32nd are lost when typing "fast" (copy/paste or writing to the uart using automated tools). This was tested on Linux 6.0, however it does not look like a brand new regression, kernel 5.4 was somehow subject to the same issue, although it was way more difficult to trigger it. While I do understand that without flow control this is something that cannot be prevented, it is pretty fishy that is always the chars after the 32nd. I guess that might be happening is that the FIFO is emptied only by a timer or when it is full, instead of emptying it when half-full, and the CPU might not be fast enough leading to an overflow and the chars lost. Any idea? Francesco
